Pack Your Own Food
We know that it's a pain to pack a sandwich in addition to packing your luggage, but bringing your own food will really will be cheaper and healthier. Often, even our favorite restaurant chains offer higher prices, and limited menus, in airports. Consider: An entree in an airport restaurant can easily cost $13, whereas a homemade turkey breast sandwich is about $2. Do that even four times per year, and you've saved $44.
